Benefits of technology
The present invention provides a method for making a heat exchanger that is better than existing methods. The goal is to make a heat exchanger that works better.
Problems solved by technology
A disadvantage of the devices and methods from the prior art is, in particular, that complicated mounting racks, which are each designed for a specific heat exchanger, have to be produced for the fixing of the elements to one another for brazing and welding.
The brazing processes for a heat exchanger often take several ten minutes to several hours and are also very energy-intensive.
Moreover, the brazing materials used are very expensive.
Furthermore, brazing methods and welding methods are not suitable for bonding just any materials, which severely limits the material selection for the elements of the heat exchanger and the possible material combinations.
When using adhesives, it is disadvantageous that the adhesives have to be laboriously applied to the elements that are to be connected, which can be done, for example, by injection devices and / or spraying devices.
Furthermore, the adhesive surfaces thus produced are either unevenly subjected to the adhesive or a very large amount of the adhesive is applied because the layer thicknesses of the adhesives are partly above 2 mm.
As a result, the required curing time is also increased, which causes the production process to become more time-consuming and costly.

Embodiment Construction
[0059]FIG. 1 shows a sectional view through a heat exchanger 1. The heat exchanger 1 has a tube 2, to which a fin member 3 is connected. The fin member 3 is connected to the tube 2 by means of an adhesive layer 4, the adhesive layer 4 being formed by an adhesive film 4 which is arranged on the outer surface of the tube 2.
[0060]The adhesive film 4 can be laminated onto the tube 2, i.e., connected to the tube 2 with the aid of an adhesive, or simply placed on the outer surface of the tube 2.
[0061]In the exemplary embodiment of FIG. 1, the fin member 3 is formed by a corrugated fin member 3. In alternative embodiments, fin-shaped members which are otherwise formed can also be provided in order to increase the outer surface area of the tube that is effective for the transfer of heat.
[0062]FIG. 1 shows only a limited partial view of the heat exchanger 1. Via the elements depicted in FIG. 1, the heat exchanger 1 can also have further tubes and fin members. The tubes can also advantageousl...

A method of producing a heat exchanger is provided that includes a connection between two elements of a heat exchanger, the two elements being connectible to each other in at least one respective contact surface. An adhesive film is applied to at least one of the elements in the region of the respective contact surface, two elements being brought in contact with each other by applying pressure and an adhesive bond being produced between the elements by means of the adhesive film. An associated heat exchanger is also provided.
Description
[0001]This nonprovisional application is a continuation of International Application No. PCT / EP2015 / 070491, which was filed on Sep. 8, 2015, and which claims priority to German Patent Application No. 10 2014 218 694.3, which was filed in Germany on Sep. 17, 2014, and which are both herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The invention relates to a method for producing a heat exchanger. The invention also relates to a heat exchanger.[0004]Description of the Background Art[0005]Heat exchangers are used to transfer heat between different fluids. For this purpose, heat exchangers of different designs are known in the prior art.[0006]The known types include, for example, heat exchangers in tube-fin design, tube bundle heat exchangers or heat exchangers in stacked plate construction. These heat exchangers have in common that they are flowed through and / or surrounded by fluids, causing heat transfer to occur between the fluids involved....
